i just had a problem with my tacoma. i drive 2 to 3 hours every few weekends. well i was driving back from school today
its cold and i had a fluttering issue. happens from about 1500rpm-2200rpm so im trying to figure out what it is.
i would assume its a cold air issue? i have the deck plate on it open. and its freezzing balls up here in nebraska.

could it be the deck plate? or a possiable vacume leake?
if you have had this problem please reply. i want to figure out this truck!
